no soap-boxes or ego trips, just good helpful advice and gives due credit to
all of the experts working in this field.

Gretchen
Fathauer, Treating Founder (Chronic Laminitis) without Horseshoes
This excellent site has huge amounts of information for anyone seeking answers
about laminitis and founder.
Based on the work of Dr Strasser, but it does include
a lot of information from other sources. The site is a bit heavy on blood and
scarey coloured photos; but if you actually have a horse with chronic or acute
laminitis, it is essential reading. It is an enormous site with many hours of
study if you follow the whole amount of material and links. http://www.naturalhorsetrim.com

Natural
Balance Hoofcare
Gene Ovnicek, farrier: Some great stuff on trimming for Barefoot hidden in between
a lot of shoeing information.
I use Gene's "Live Sole Plane Reference" (though
I prefer to call it "Natural Sole Plane") all the time!!! I can strongly recommend
Gene's video "Natural Balance Hoof Trimming". http://www.hopeforsoundness.com

Dr Chris Pollitt, University of Queensland.
Absolute world leader in research on equine feet (and a lot of other veterinary
subjects). http://www.uq.edu.au/~apcpolli/

Not
for the fainthearted: Full of scientific language, but essential for in depth
study:
